Need help making XML and Java work toget

I’ve been attempting to use the project cool xml earthquake script
http://www.devx.com/projectcool/developer/behaviors/earthquake.html
in conjunction with a simple rollover:

so i’d have that enclosed in the tags— however, the page doesn’t like having that added onmouseover from the rollover script.

how would i go about implimenting the rollover into the .htc file, or what other options do i have to get both the earthquake behavior and the image rollover???
thanks.
